[gtk+] Store the buildable name in object data instead of the widget name

[Christian Dywan <cdywan src gnome org>]

commit 46f5ee1d0c0f4601853ed57e99b1b513f1baa445

    Store the buildable name in object data instead of the widget name
    
    Widget names are used for theming which is why GtkBuilder should
    use object data.
